Import Diamond Grade Reflective Sheeting — Buy in Bulk from Supplier in China

The Diamond Grade Reflective Sheeting offered by Derflex is a high‑hardness polycarbonate film designed for retroreflection on traffic signage. It complies with the first and second grade requirements of China’s JT‑T279‑1995 standard for reflective materials. Each square centimetre of the film contains more than 930 micro‑crystal cubes that create internal total reflection without a metallic layer. The film delivers a brightness that is over six times that of conventional engineering‑grade reflective films and three times that of high‑grade variants.

Unlike engineering‑grade films that rely on glass beads, the diamond grade film uses crystallite cube technology, a method recognised for its wide‑angle performance. The polycarbonate substrate gives the sheet wear resistance and maintains optical properties under normal traffic conditions. Typical reflective sheeting in the market is supplied in thicknesses from 0.2 to 0.5 mm and achieves reflectivity levels of 150‑200 cd/lx, which aligns with the performance of this product. Under the standard operating temperature of 18 °C to 28 °C the material retains its structural integrity.

The sheeting is suited for guide, prohibition, warning and indication signs on high‑grade highways and urban roads, as well as for advertising panels that require durable retroreflection. Road authorities, sign manufacturers and construction contractors are the primary buyers of this film. Derflex does not publish minimum order quantities, pricing or lead‑time, so interested importers should request a formal quotation and confirm Incoterms and payment conditions directly with the supplier. The supplier’s listed verification tier is “harbor”, indicating a basic level of platform verification.
